Product Description

Contains triclabendazole, a flukicide for the specific treatment and control of liver fluke (Fasciola hepatica) infections in sheep.

When used at the recommended dose rate Fasinex is effective against all stages of triclabendazole susceptible F. hepatica from 2 day old early immature forms to adult fluke.


Dosage & Administration

  • Fasinex 5% is given as an oral drench and is suitable for use through most types of automatic drenching guns.
  • Fasinex can be safely given to young, pregnant or stressed sheep.
  • Recommended dose rate: 1 ml Fasinex 5% per 5kg bodyweight.
  • For each additional 5kg add 1 ml to dose.


Routine flock treatment (high risk fluke areas):

  • As a guide, dose all sheep exposed to fluke infected pastures preventatively at regular intervals of 10 weeks from March/April through to October/November.
  • A dose in January may also be required.
  • All animals grazing the pasture should be treated at these times.
  • Any bought-in sheep should be dosed before joining the main flock.
  • Veterinary advice should be sought with regard to specific preventative dosing regimes.

Routine flock treatment (moderate risk fluke areas):

  • Dose all sheep exposed to fluke infested pasture at regular intervals of 10 weeks throughout the fluke season, usually from September to January/February.
  • An additional preventative treatment in the Spring will assist in reducing the amount of new infection on pasture in the following autumn.
  • Any bought-in sheep should be dosed before joining the main flock.

Treatment of acute outbreaks

  • The flock should be treated immediately after diagnosis is reached.
  • Veterinary advice should be sought for subsequent dosing intervals.


  • Meat - Animals must not be slaughtered for human consumption during treatment.
  • Sheep may be slaughtered for human consumption only after 56 days from last treatment.
  • Milk - Do not administer to animals producing milk intended for human consumption.
